To solve the expression \( \frac{9}{10} + \frac{1}{2} \), we need to find a common denominator before adding the fractions.

1. The denominators are 10 and 2. The least common denominator (LCD) is 10.
2. Convert \( \frac{1}{2} \) to have a denominator of 10:  
   \[
   \frac{1}{2} = \frac{1 \times 5}{2 \times 5} = \frac{5}{10}
   \]
3. Now, add the fractions:
   \[
   \frac{9}{10} + \frac{5}{10} = \frac{9 + 5}{10} = \frac{14}{10}
   \]
4. Simplify the fraction \( \frac{14}{10} \):
   \[
   \frac{14}{10} = \frac{7}{5} = 1.4
   \]

So, the final result is \( \frac{7}{5} \) or 1.4.

Would you like more details or have any questions? Here are five related questions:

1. How do you add \( \frac{3}{4} + \frac{1}{2} \)?
2. What is the sum of \( \frac{7}{10} + \frac{3}{5} \)?
3. How do you subtract \( \frac{9}{10} - \frac{1}{2} \)?
4. Can you simplify the fraction \( \frac{14}{10} \) further?
5. How do you multiply \( \frac{9}{10} \times \frac{1}{2} \)?

**Tip:** When adding or subtracting fractions, always find the least common denominator (LCD) first.
